FIG. 33 is a flowchart of a method of scrolling a plurality of windows when the plurality of windows are displayed on a screen, according to one or more exemplary embodiments;

A device may provide an execution result of an application, which is being executed by the device, to the plurality of windows that are displayed in at least two modes by a touch input, display the plurality of windows, which show execution results of the plurality of windows, on a screen of the device by arranging the plurality of windows to be adjacent to each other, receive a user input when the plurality of windows are displayed on the screen, and scroll the plurality of windows in correspondence with a user input. The user input may be a flick gesture. The flick gesture is an operation by which a user contacts a part of a body or an input apparatus of a user (for example, a touch pen) to a screen that may detect a touch and, while maintaining the touch, moving the part of the body or the input apparatus in a certain direction.

Referring to FIG. 33, in operation S3310, the device provides an execution result of an application that is being executed in a window. As the device provides the execution result of an application that is being executed to the window, the execution result of the application that is being executed may match the window and may be displayed in the window. Additionally, the window may be displayed in at least two modes according to a user input. For example, a display mode of the displayed window may include a first mode, a second mode, and a third mode. A user input may be a touch input. Alternately, a user input may be a tap gesture input. The device may generate a window band by arranging a plurality of windows to be adjacent to each other and display the generated window band on a screen of a display.

An execution result of an application that is being executed may be displayed in each of the plurality of windows that constitute the window band. The execution result may include various objects according to an application, and an execution result of one application may be displayed in one window. Additionally, an execution result of one application may be displayed in the plurality of windows. For example, if an application for displaying weather information is executed, weather information may be displayed in one window. If a game is executed, a screen of the game may be displayed in a first window, and a button for controlling the game may be displayed in a second window.

A window may be displayed in at least two display modes. A display mode of the window may include a first mode and a second mode. A display of the window may further include a third mode. Additionally, according to a display mode of the window, a size of the window or a type of data displayed in the window may vary. For example, the window may display first data in the first mode, and the first data and second data in the second mode. The window may be displayed with a smaller size in the first mode than in the second mode. For example, the window may include a reduced mode or a general mode. The reduced mode may be the first mode. The general mode may be the second mode. If the device receives a tap gesture to one window from among the plurality of windows when the plurality of windows are displayed in the first mode, in correspondence with the tap gesture, the window may be displayed in an uppermost part of the plurality of windows. A tap gesture may be a single tap or a double tap. For example, windows A through E may be sequentially displayed in a first mode from an upper part of the screen of the device. In this case, the windows A through E may constitute a window band. If a user taps the window C located in the middle of the windows A through E when the window band, formed of the windows A through E, is displayed, the device may display the window C at an uppermost part of the window band. The windows in the window band may be disposed in an order of the windows C, A, B, D, and E. In other words, the windows C, A, B, D, and E may be sequentially displayed from an upper part. Additionally, the window C may be displayed to have an increased size in a second mode, and the other windows A, B, D, and E may be displayed in a first mode.

The display mode of the window may include the third mode. The third mode may be an expanded mode. A size of the window may be changed to be displayed according to the display mode. When the display mode of the window is a first mode, the window may have a smallest size, and when the display mode of the window is a second mode, the window may have a medium size. When the display mode of the window is a third mode, the window may have the biggest size. The window may be displayed in the first mode, the second mode, or the third mode. Accordingly, the window band may be displayed in the first mode, the second mode, and/or the third mode. For example, the windows A and B that constitute the window band may be displayed in the first mode, the windows C and D may be displayed in the second mode, and the window E may be displayed in the third mode. The window band is arranged when a plurality of windows are adjacent to each other.

The window may switch to the first mode, the second mode, or the third mode according to a user input. The first mode may be a reduced mode, the second mode may be a general mode, and the third mode may be an expanded mode. For example, if a user inputs a pinch zoom-out gesture to the window band that is displayed in the reduced mode, the device may display a plurality of windows that constitute the window band as a general mode. When the plurality of windows are displayed in a general mode, if the user taps one of the plurality of windows, the device may display a window, which is shown on a location where a tap gesture is received, in an expanded mode.

In the reduced mode, first data may be displayed in the window. The first data may include a name of an application. Additionally, the first data may include a name of the window. The name of the window may be a name of an application that is being executed. In the reduced mode, a name of the application may be displayed in the window.

In the general mode, the first data and the second data may be displayed in the window. In the general mode, the second data may be further displayed in addition to data that is displayed in the reduced mode. The second data may include an execution result of an application and an icon that corresponds to the application. For example, a name of an application, an icon that corresponds to the application, and content related to the application may be displayed in the window in a general mode. Content may be an execution result of the application. Content may include a plurality of items. If a user touches the icon in the general mode, the application may be displayed in a whole screen of the display.

In the expanded mode, the first data, the second data, and the third data may be displayed in the window. In the expanded mode, the third data may be further displayed in addition to the data that was displayed in the general mode. For example, a name of an application, an icon that corresponds to the application, content related to the application, and additional information about the content may be displayed in the window in the expanded mode. The additional information about the content may not be displayed in the general mode. For example, if weather information about a particular local area and a particular date is displayed in the window that is shown in the general mode, weather information for a week may be displayed in the expanded mode, in addition to the particular local area and the weather information about the particular date.

Each window that constitutes the plurality of windows may be displayed with a smaller size in the reduced mode than in the general mode. Each window that constitutes the plurality of windows may be displayed with a smaller size in the general mode than in the expanded mode.

In operation S3320, the device may arrange a plurality of windows to be adjacent to each other, and the arranged plurality of windows may be displayed on a screen of the display of the device.

Referring to (a) of FIG. 34, a status bar 3401, a plurality of windows 3403, 3405, and 3407, and an app dock 3410 are shown. A status of the device and a current time may be displayed in the status bar 3401. The status bar 3401 may be displayed fixed on a screen of the device, and even if the plurality of windows 3403, 3405, and 3407 are scrolled, the status bar 3401 may not disappear and may be displayed on the screen of the device.

The plurality of windows 3403, 3405, and 3407 may constitute the window band and may be displayed in a general mode. Each window may be displayed in a reduced mode, a general mode, or an expanded mode, and according to each mode, the window may be displayed with different sizes. A size of the window may be changed according to at least two steps according to a user input. A user input may be a touch and/or gesture input. For example, when a plurality of windows are displayed in a general mode, if a user taps, and thus, selects one of the plurality of windows, the device may change the selected window to be displayed in an expanded mode. Additionally, for example, when a plurality of windows are displayed in a general mode, if a user taps one of the plurality of windows, the device may change the plurality of windows to be displayed in an expanded mode.

Additionally, an execution result of the application that is being executed may be displayed in the window. A controller may provide an execution result of the application to the window, so that the execution result of the application may be displayed on a screen. The plurality of windows 3403, 3405, and 3407 may be arranged to be adjacent to each other. A window band may be formed by disposing the window 3405 to be adjacent to and below the window 3403, and disposing the window 3407 to be adjacent to and below the window 3405. If a user performs a flick operation on a screen in an upward or downward direction, the plurality of windows may be scrolled in an upward or downward direction. For example, while the plurality of windows displayed in a general mode are being scrolled, the plurality of windows may be displayed with a smaller size than in the general mode.

While the plurality of windows is being scrolled, the app dock 3410 may not be displayed. Additionally, if the plurality of windows are scrolled to an end and a certain user input is received, the app dock 3410 that has disappeared may be displayed on the screen. An icon that corresponds to the application may be displayed in the app dock 3410. If a user performs a flick operation on the icon displayed in the app dock 3410 in a left or right direction, the icon may be scrolled in an upward or downward direction.

(b) of FIG. 34 is a diagram illustrating a status in which a plurality of windows 3403 a, 3405 a, 3407, 3409, 3411, 3413, and 3415 are scrolled. Referring to FIG. 34B, the status bar 3401 and the plurality of windows 3403 a, 3405 a, 3407, 3409, 3411, 3413, and 3415 are shown. As a user performs a flick operation on a screen in an upward or downward direction, the plurality of windows 3403 a, 3405 a, 3407, 3409, 3411, 3413, and 3415 may be scrolled. While the plurality of windows 3403 a, 3405 a, 3407, 3409, 3411, 3413, and 3415 are being scrolled, the plurality of windows 3403 a, 3405 a, 3407, 3409, 3411, 3413, and 3415 may have different sizes according to an area of the screen in which the plurality of windows 3403 a, 3405 a, 3407, 3409, 3411, 3413, and 3415 are displayed. For example, if the windows 3403 a, 3405 a, and 3407 are scrolled in an upward direction, the windows 3409, 3411, 3413, and 3415 may be newly displayed on a lower part of the window band. Additionally, the plurality of windows 3403 a, 3405 a, 3407, 3409, 3411, 3413, and 3415 may move from a lower part of the window band to an upper part of the window band through a center of the window band. As each window moves to the upper part, a size of each window gradually increases. Then, if each window is placed at an uppermost part of the window band, each window may be covered by a window placed below, and thus, disappear from the screen.

If a user performs a flick operation on the plurality of windows to an upper part of the screen, each window may move from a lower part to an upper part of the screen. If the window is in the lower part of the window band, the window may have a small size. Then, when the window moves through approximately a center part of the screen, a size of the window increases largest. Then, as the window moves upwards, a size of the window decreases, and then, the window may disappear from the screen. For example, the windows 3413 and 3415, displayed on a lower part of the screen, may be smaller than the window 3411. Additionally, the window 3411 may be smaller than the window 3409. Additionally, the window 3409 may be smaller than the window 3407. The window 3407 placed in a center part may be the biggest and may be displayed in a general mode. As the windows are scrolled in an upward direction, the window placed in an upper location may be gradually covered by the window placed in a lower location, and thus, may disappear from the screen. The window 3403 a may be covered by the window 3405 a placed below, and thus, only a part of the window 3403 a may be displayed. The window 3403 a may be covered by the window 3405 a placed below, and thus, only a part of the window 3403 a may be displayed. While the plurality of windows are scrolled, the app dock 3410 may not be displayed, and a dot 3410 a that corresponds to the app dock 3410 may be displayed on the screen. Even after the scrolling is finished, the dot 3410 a may be still displayed on the screen. If a user touches the dot 3410 a displayed on the screen, the app dock 3410 may be displayed on the screen.

FIG. 35 is a flowchart of a method of receiving a tap gesture with respect to one window from among a plurality of windows displayed in a general mode and, in correspondence with the tap gesture, displaying the window in an expanded mode, according to one or more exemplary embodiments.

Referring to FIG. 35, in operation S3510, when a plurality of windows are displayed in a general mode, a device receives a tap gesture from one of a plurality of windows. In operation S3520, in correspondence with the tap gesture, the device may display the window in an expanded mode. The device may expand and display the window that is displayed on a location where the tap gesture is input. As the window is displayed in an expanded mode, a window adjacent to the window, which is displayed in the expanded mode, may be displayed smaller than in a general mode. For example, when three windows A, B, and C are arranged to be adjacent to each other in a screen, if the window B disposed in a middle thereof is tapped, the window B is displayed in an expanded mode, and the windows A and C are reduced and displayed with a smaller size than in the general mode.

An example in which a window displayed in a general mode is displayed in an expanded mode according to a tap gesture has been described. However, exemplary embodiments are not limited to a tap gesture. As a non-limiting example, according to a rule preset by a device, a window displayed in a general mode based on a touch input and a touch and hold gesture input may be displayed in an expanded mode.

If a window displayed in a general mode is displayed in an expanded mode according to a tap gesture input by a user, a direction in which the window is expanded may vary according to a location of the window displayed in the general mode. If the device receives a tap gesture by a user when the window displayed in the general mode is displayed above a center of the screen, the device may expand and display the window in a lower direction. If the device receives a tap gesture when the window displayed in the general mode is displayed below the center of the screen, the device may expand and display the window in an upper direction.

Referring to (b) of FIG. 36, the status bar 3601 and a plurality of windows 3603 a, 3605 a, 3607 a, 3609 a, and 3611 a are shown. As the window 3605 a is displayed in an expanded mode, the other windows 3603 a, 3607 a, 3609 a, and 3611 a may be displayed in a reduced mode. In this case, the app dock 3610 may disappear from the screen, and a dot 3610 a that corresponds to the app dock 3610 may be displayed on the screen. If a window is expanded, a direction in which the window is expanded may vary according to a location where the window is displayed. If the controller receives a tap gesture input when the window is placed above a center of the screen, the controller may expand and display the window in a lower direction. If the controller receives a tap gesture input when the window is placed below the center of the screen, the device may expand and display the window in an upper direction. For example, if the window 3607 is tapped, the window 3607 may be expanded in an upper direction. If the window 3603 is tapped, the window 3603 may be expanded in a lower direction.

In the reduced mode, a name of an application may be displayed in a window. Only a name of an application may be displayed in the reduced mode, due to a limited space in the window. More information may be displayed in a general mode than in the reduced mode.

The plurality of windows 5124, 5126, 5128, 5130, 5132, 5134, and 5136 are displayed adjacent to each other. The window 5124 that is a second window is displayed in the second mode. The other windows 5126, 5128, 5130, 5132, 5134, and 5136 are displayed in the first mode. The first mode may be a reduced mode. The second mode may be a general mode.

The second window 5124 may work with the first window 5122 and may be displayed in the general mode. The second window 5124 may be displayed in an upper part of a screen, compared to the other windows 5126, 5128, 5130, 5132, 5134, and 5136. The device may move the second window 5124 that may work with the first window 5122 and display the second window 5124 in an upper part of the screen. Even when the second window 5124 is not displayed on the screen, the device may move and display the second window 5124 in an upper part of the screen.

For example, though the second window 5124 was not originally displayed in the screen, as the second window 5124 works with the first window 5122, the second window 5124 may be moved to and displayed in an upper part of the screen.

Additionally, the device may display the second window 5124, which may work with the first window 5122, to be adjacent to the first window 5124. If the first window 5104 is placed in an upper part of the screen, the second window 5124 that may work with the first window 5122 may be moved to and displayed in an upper part of the screen. If the first window 5122 is placed in a middle of the screen, the second window 5124 that may work with the first window 5122 may be moved to and displayed in a middle of the screen. If the first window 5122 is placed in a lower part of the screen, the second window 5124 that may work with the first window 5122 may be moved to and displayed in a lower part of the screen.

Referring to (c) of FIG. 51, a first window 5142 is displayed to overlap with a plurality of windows 5144, 5146, 5148, 5150, 5152, 5154, 5156, and 5158. The plurality of windows 5144, 5146, 5148, 5150, 5152, 5154, 5156, and 5158 are displayed adjacent to each other. A second window that may work with the first window 5142 is not displayed on the screen.

An object 5159 for showing the number of windows that may work with the first window 5142 may be displayed in a lower part of the screen. For example, the object 5159 may be an image in a shape of an arrow. The object 5159 may provide information about a location of the second window that may work with the first window 5142 with reference to a current screen and information about the number of second windows. For example, with reference to the current screen, if two second windows that may work with the first window 5142 are present in a lower part of the screen, the object 5159 may be displayed to be directed downwards, and “2” may be displayed in the object 5159. Additionally, for example, with reference to the current screen, if three second windows that may work with the first window 5142 are present in an upper part of the screen, the object 5159 may be displayed to be directed upwards, and, for example, “3” may be displayed in the object 5159.

When “2” is displayed in the object 5159 that is directed downwards, if a user scrolls a plurality of windows in a downward direction, two second windows that may work with the first window 5142 may appear.

Additionally, if a plurality of second windows that may work with the first window 5142 are present, the second windows may be displayed in an order of priority. Additionally, if a plurality of second windows that may work with the first window 5142 are present, the second windows may be displayed in a nearby area of the first window in an order of a priority. In this case, a priority in which the second windows work with the first window may be determined based on a degree of association between the first window and the second windows. For example, a priority may be determined according to the number of times the first window 5142 and the second windows have worked with each other, and thus, employed by a user, and a degree of redundancy of data displayed in the first window 5142 and data displayed in the second windows.

Referring to (d) of FIG. 51, a first window 5162 is displayed to overlap with a plurality of windows 5164, 5166, 5168, 5170, 5172, and 5174. The windows 5164, 5166, and 5168 are displayed in the second mode. The windows 5170, 5172, and 5174 are displayed in the first mode. The second mode may be a general mode. The first mode may be a reduced mode. The windows 5162, 5264, and 5168 that are second windows that may work with the first window 5162 may be displayed in a general mode. If a plurality of the second windows 5162, 5264, and 5168 are present, an order of displaying the second windows 5162, 5264, and 5168 may be determined according to a priority of working with the first window 5162. A priority may be preset for each application. For example, the window 5164 from among the second windows 5164, 5266, and 5168 that may work with the first window 5162 has a highest priority and may be displayed in an uppermost part of the screen. The window 5166 has a second highest priority and may be displayed below the window 5164. The window 5168 has a third highest priority and may be displayed below the window 5166.

FIG. 52 is a diagram illustrating an example in which a plurality of windows that may work with each other are provided in a pre-combined form.

The device may form a combination of a plurality of windows that may work with each other for a preset number of times and used, and display a preview image in which a plurality of windows are combined on a screen. The device may generate a combination of a plurality of windows in advance by analyzing a history of an application for which a plurality of windows were executed to work with each other and provide a preview image to the screen.

Referring to (a) of FIG. 52, a UI 5202 for combining windows is displayed. If a user selects a plurality of windows via the UI 5202, the device may display a preview image, in which the plurality of windows are combined in advance, on the screen.

Referring to (b) of FIG. 52, preview images 5222, 5224, and 5226, in which a plurality of windows are combined, are displayed. Two windows 5204 and 5206 are combined in the preview image 5222, and the windows 5204 and 5206 may work with each other.

Three windows 5212, 5214, and 5216 are combined in the preview image 5226, and the windows 5212, 5214, and 5216 may work with each other.

Text for providing information about a window combination may be displayed below each of the preview images 5222, 5224, and 5226. For example, “Music+Youtube” is displayed below the preview image 5222.

When the plurality of windows are combined in advance and apps executed in each window are executed to work with each other, information about the apps that may work with each other may be written to each app. Additionally, the device may store a history that a plurality of apps worked with each other and were executed in a separate file. For example, if an app A and an app B are executed to work with each other, the device may write identification values of the app A and the app B, and information regarding how the app A and the app B work with each other.

If a user selects one of the preview images 5222, 5224, and 5226, a plurality of windows that correspond to the selected preview image may work with each other, and a result that a plurality of apps were executed to work with each other may be displayed in each window. For example, if a user selects the preview image 5222, the windows 5204 and 5206 may work with each other and a result that two apps were executed to work with each other may be displayed in the window 5204 and 5206, as shown in (c) of FIG. 52.

Referring to (c) of FIG. 52, the window 5204 and the window 5206 work with each other and displayed. An app execution result, with reference to an app executed in the window 5204, may be displayed in the window 5206. For example, if music “A” is played in the window 5204, a music video for the music “A” may be displayed in the window 5206 that is executed to work with the window 5204.

FIG. 53 is a diagram illustrating a result in which a plurality of apps are executed to work with each other. If the plurality of apps are executed to work with each other, the device may read data from one of the plurality of apps that are executed to work with each other and provide the data to another app. Additionally, the device may filter a result displayed by the other app, based on the data provided to the other app.

Referring to (a) of FIG. 53, a plurality of windows 5302, 5304, 5306, and 5308 are displayed on a screen. The plurality of windows 5302, 5304, 5306, and 5308 work with each other.

FIG. 54 is a flowchart of a method of executing a first application to work with a second application according to a user input of moving an icon of a first application to an icon of a second application, according to one or more exemplary embodiments.

Referring to FIG. 54, in operation S5400, the device 1000 may receive a user input of selecting the icon of the first application. A user of the device 1000 may select the first application by touching the icon of the first application displayed on an application tray. In this case, the application tray may be displayed on a screen of the device 1000, e.g., according to a user input of touching an edge of the screen and dragging the edge of the screen toward a center of the screen of the device 1000. Additionally, the device 1000 may select the first application, by selecting the icon of the first application displayed on an application screen.

Alternatively, the device 1000 may select the icon of the first application by receiving a user input of touching the icon of the first application and dragging the icon in a particular direction. For example, the device 1000 may receive a user input of touching and dragging the icon of the first application displayed on the application tray. Additionally, for example, the device 1000 may receive a user input of touching and dragging the icon of the first application displayed on the application screen.

In operation S5410, the device 1000 may display an icon of a second application that may be executed to work with the first application, such that the icon is distinguished from other icons. As an event in which a user touches and drags the icon of the first application in a particular direction occurs, the device 1000 may display the icon of the second application from among a plurality of icons included in the application tray, such that the icon is distinguished from other icons.

For example, the device 1000 may change and display a color or a thickness of an edge of the icon of the second application that may be executed to work with the first application. Additionally, for example, the device 1000 may display the icon of the second application as three dimensional (3D). Additionally, for example, the device 1000 may display the icon of the second application to be brighter than other icons. However, it is understood that one or more other exemplary embodiments are not limited thereto.

The second application that may be executed to work with the first application may be an application that may use a function or data of the first application. The data of the first application may include data input via the first application or data collected by the first application.

The device 1000 may identify a second application that may work with the first application, based on an identification value, a type, and data of the first application. For example, a second application that may be executed to work with the first application may be preset, based on the identification value or the type of the first application, and the device 1000 may identify the second application that may be executed to work with the first application, based on the presetting of the second application.

Additionally, the device 1000 may identify a second application that may work with the first application, by determining whether the second application may use data corresponding to the icon of the first application. The data corresponding to the icon of the first application may be variously set as, for example, an identification (ID), an e-mail address, a location, or a phone number of a particular person, or a date.

For example, if data corresponding to a contact information icon of a contact information application is user information of a particular user, it may be determined that a map application that may display a location of the particular user may be executed to work with the data corresponding to the contact information icon. The contact information icon may be an icon for making a phone call to a phone of the particular user. For example, the device 1000 may make a call to a phone of a particular person by using a phone number corresponding to the contact information icon. However, the data corresponding to the contact information icon of the contact application is not limited thereto. If the data corresponding to the contact information icon of the contact application is user information of a particular user, it may be determined that, for example, a clock application that may display time in a place where the particular user is located, a weather application that may display weather in a place where the particular user is located, a social network service (SNS) application that may share information with the particular user, a gallery application that may display a photograph which includes the particular user, or an e-mail application that may transmit an e-mail to the particular user may be executed to work with the data corresponding to the contact information icon.

In detail, the device 1000 may transmit data of the first application to the second application, and the second application may determine whether the first application and the second application may work with each other, by using the transmitted data of the first application. The second application may calculate a result value of a particular function by using the data of the first application as an input value. Then, the device 1000 or the second application may determine whether the second application may use the data of the first application based on the calculated result value. For example, at least one of a phone number, an e-mail address, and a user ID corresponding to the contact information icon may be transmitted to a map application, and the map application may calculate a result value of a particular function by using the at least one of the transmitted phone number, e-mail address, and user ID as an input value. Additionally, the device 1000 or the map application may determine whether the map application may use the at least one of the phone number, the e-mail address, and the user ID corresponding to the contact information icon, based on the calculated result value.

Additionally, the device 1000 or the second application may determine whether the first application and the second application may work with each other based on an attribute of the data of the first application. The attribute of the data of the first application may include a type and a form of the data of the first application. The second application may check the type and the form of the data of the first application, and determine whether the data of the first application has such a type and a form that may be processed by the second application. The second application may determine whether the second application may perform a certain function by using the data of the first application.

It is understood that, according to one or more exemplary embodiments, there may be a plurality of second applications that may be executed to work with the selected first application. In this case, icons for the plurality of second applications may be displayed to distinguish over icons of other applications that may not be executed to work with the selected first application.

In operation S5420, the device 1000 may receive a user input of moving the icon of the first application to the icon of the second application. The device 1000 may receive a user input of dragging and dropping the icon of the first application to the icon of the second application.

In operation S5430, the device 1000 executes the second application to work with the first application. The device 1000 may control the second application to perform a function related to the first application, from among functions of the second application. The device 1000 may control the second application to use a function of the first application. Additionally, the device 1000 may control the second application to use the data of the first application. In this case, the second application may be executed in a background of the device 1000 and use the data of the first application. For example, if a contact information icon is dragged & dropped to the icon of the map application, the map application may be executed in the background, and user information of a particular user corresponding to the contact information icon may be used by the map application that is executed in the background.

It is described herein that the device 1000 executes the first application to work with the second application as the icon of the first application is dropped to the icon of the second application. However, it is understood that the executing of the second application and the first application to work with each other is not limited thereto. For example, if the icon of the first application and the icon of the second application are located together in a particular area of a screen of the device 1000 or within a predetermined distance of each other, the device 1000 may execute the first application to work with the second application. In this case, the particular area of the screen of the device 1000 may be, for example, an area within a certain boundary or an area in a separate window, but is not limited thereto.

In operation S5440, a result of executing the second application to work with the first application may be displayed in a periphery of the icon of the second application. The device 1000 may display the result of executing the second application to work with the first application in a periphery of the icon of the second application. The second application may obtain association information by using the data corresponding to the icon of the first application, and display the obtained association information in a periphery of the icon of the second application. In this case, the second application may be executed in the background of the device 1000. Additionally, the association information may be one piece of information from among pieces of information indicating a result of performing a function related to the first application, from among functions of the second application.

For example, if the icon of the first application is the contact information icon and the second application is the map application, the device 1000 may obtain current location information of a user corresponding to the contact information icon, and display the obtained location information in a periphery of the icon of the map application. Additionally, for example, if the icon of the first application is the contact information icon and the second application is the clock application, the device 1000 may obtain time information indicating a current time in a current location of a user corresponding to the contact information icon, and display the obtained time information in a periphery of the icon of the clock application. Additionally, for example, if the icon of the first application is the contact information icon and the second application is the SNS application, the device 1000 may obtain information indicating a number of new messages for a user corresponding to the contact information icon, and display the obtained information in a periphery of the icon of the SNS application. Additionally, for example, if the icon of the first application is the contact information icon and the second application is the e-mail application, the device 1000 may obtain information indicating a number of e-mails transmitted from a user corresponding to the contact information icon to a user of the device 1000, and display the obtained information in a periphery of the icon of the e-mail application.

The device 1000 may display the window band on the screen of the device 1000 by generating a plurality of windows that show the execution result of the application that is being executed and arranging the plurality of windows to be adjacent to each other.

The window band may include, for example, a lock band, a home band, and an application band. The device 1000 may display a lock band on a lock screen and display a home band on a home screen. The device 1000 may display an application band on an application screen.

In operation S5510, the device 1000 may detect a user's touch input to an edge of the screen of the device 1000. For example, the device 1000 may detect a user input of touching an edge of the screen of the device 1000. Alternatively, for example, the device 1000 may detect a user input of touching an edge of the screen of the device 1000 and dragging the edge of the screen to a center of the screen. However, it is understood that the user's touch input is not limited thereto.

In operation S5520, the device 1000 may display a list of icons of applications at the touched edge of the screen. The device 1000 may display an application tray at the touched edge of the screen. For example, if the user touches a left edge of the screen of the device 1000, the device 1000 may display an application tray that includes a list of icons of applications along the left edge of the screen of the device 1000.

In operation S5530, the device 1000 may receive a user input of touching and dragging the icon of the first application in the list of the icons of the applications. For example, the device 1000 may receive a user input of touching and dragging a contact information icon, from among the icons in the application tray.

In operation S5540, the device 1000 may display at least one icon of at least one application that may be executed to work with the first application, such that the at least one icon is distinguished from other icons. If the device 1000 detects a user input of touching and dragging the icon of the first application from the list of the icons of the applications, the device 1000 may display the at least one icon of the at least one application that may be executed to work with the first application, such that the at least one icon is distinguished from the other icons in the list of the icons of the applications. According to one or more other exemplary embodiments, the device 1000 may display a new list (i.e., different from the list of the icons of the applications from which the icon of the first application is selected) of at least one icon of the at least one application that may be executed to work with the first application.

The at least one application, which may be executed to work with the first application, may be an application that may use a function of the first application or an application that may use data of the first application. The data of the first application may include data input via the first application or data collected by the first application. Additionally, for example, the device 1000 may change and display a color or a thickness of an edge of the at least one icon of the at least one application that may be executed to work with the first application. Additionally, for example, the device 1000 may display in 3D the at least one icon of the at least one application that may be executed to work with the first application. Additionally, for example, the device 1000 may display the at least one icon of the at least one application that may be executed to work with the first application to be brighter than other icons. However, it is understood that exemplary embodiments are not limited thereto.

The device 1000 may also identify an application that may work with the first application, based on at least one of an identification value, a type, and data of the first application. For example, an application that may be executed to work with the first application may be preset, based on the identification value or the type of the first application, and the device 1000 may identify an application that may be executed to work with the first application, based on a presetting for the application.

Additionally, the device 1000 may transmit the data of the first application to an application other than the first application, and the other application may determine whether the first application may work with the other application, by using the transmitted data of the first application.

The other application may calculate a result value of a particular function by using data of the first application as an input value. Then, the device 1000 or the other application may determine whether the other application may use the data of the first application, based on the calculated result value. For example, at least one of a phone number, an e-mail address, and a user ID corresponding to a contact information icon may be transmitted to a map application, and the map application may calculate a result value of a particular function by using the at least one of the phone number, the e-mail address, and the user ID corresponding to the contact information icon as an input value. Additionally, the device 1000 or the map application may determine whether the map application may use the at least one of the phone number, the e-mail address, and the user ID corresponding to the contact information icon, based on the calculated result value.

Additionally, the other application may determine whether the first application and the other application may work with each other based on an attribute of the data of the first application. The attribute of the data of the first application may include a type and a form of the data of the first application. The other application may check the type and the form of the data of the first application, and determine whether the data of the first application has such a type and a form that may be processed by the other application. The other application may determine whether the other application may perform a certain function by using the data of the first application.

In operation S5550, the device 100 may detect that the icon of the first application is dropped to the icon of the second application from among the at least one icon of the at least one application that is displayed such that the at least one icon is distinguished from the other icons. As the icon of the first application is dropped to the icon of the second application, the icon of the first application and the icon of the second application may temporarily overlap with each other.

In operation S5600, the device 1000 may determine whether to perform an operation of displaying association information. As the icon of the first application is moved to the icon of the second application, if the icon of the first application and the icon of the second application temporarily overlap with each other, the device 1000 may display a graphical user interface (GUI) for asking a user to confirm whether the device 1000 is to perform an operation of displaying the association information on the screen of the device 1000. The GUI for asking the user to confirm whether the device 1000 is to perform an operation of displaying the association information may, for example, include a button for displaying the association information and a button for moving an icon. If the user selects the button for displaying the association information, the device 1000 may determine whether to perform an operation of displaying the association information.

As a result of the determining in operation S5600, if the device 1000 determines not to perform the operation of displaying the association information, the device 1000 may move a location of the icon of the first application in operation S5610.

As a result of the determining in operation S5600, if the device 1000 determines to perform the operation of displaying the association information, the device 1000 may determine in operation S5620 whether a plurality of pieces of the data of the first application, which may be provided to the second application by the first application, are present.

As a result of the determining in operation S5620, if a plurality of pieces of the data of the first application are present, the device 1000 may display a selection list for selecting at least one of pieces of data on the screen of the device 1000 in operation S5630. The device 1000 may display the selection list in a periphery of the icon of the first application. Alternatively, the device 1000 may overlap the selection list with the icon of the first application.

For example, if the icon of the first application is a contact information icon, the device 1000 may display the selection list for selecting at least one of a phone number, an e-mail address, and a user ID of at least one a user corresponding to the contact information icon in a periphery of the contact information icon.

In operation S5640, the device 1000 may select data to be provided to the second application, based on a user input. The device 1000 may receive a user input of touching particular data in the selection list for selecting at least one selected from the plurality of pieces of data of the first application, and thus, select data to be provided to the second application.

In operation S5650, the device 1000 may provide the selected data to the second application. The device 1000 may enable the first application to provide the data, selected by the user from among the group consisting of the plurality of pieces of the data corresponding to the icon of the first application, to the second application. Alternatively, if a single piece of data corresponding to the icon of the first application is present, the device 1000 may provide the single of piece of data corresponding to the icon of the first application to the second application without having to receive a user input of selecting data.

For example, if the icon of the first application is the contact information icon and the second application is the map application, the device 1000 may enable a phone number of a user corresponding to the contact information icon to be transmitted from the contact information application to the map application.

Additionally, for example, if the icon of the first application is the contact information icon and the second application is a clock application, the device 1000 may enable address information of a user corresponding to the contact information icon to be transmitted from the contact information application to the clock application.

Additionally, for example, if the icon of the first application is the contact information icon and the second application is an SNS application, the device 1000 may enable an ID of an SNS account of a user corresponding to the contact information icon to be transmitted to the SNS application.

Additionally, for example, if the icon of the first application is the contact information icon and the second application is an e-mail application, the device 1000 may enable an e-mail address of a user corresponding to the contact information icon to be transmitted from the contact information application to the e-mail application.

Additionally, for example, if the icon of the first application is the contact information icon and the second application is a gallery application, the device 1000 may enable an image of a photograph of a user corresponding to the contact information icon to be transmitted from the contact information application to the map application.

Additionally, for example, if the icon of the first application is a map icon and the second application is the gallery application, the device 1000 may enable information indicating a current location of the device 1000 to be transmitted from the map application to the gallery application.

In operation S5660, the device 1000 may obtain association information by using the data provided to the second application. The device 1000 may enable the second application to generate association information or receive association information from outside by using the data provided to the second application.

For example, if the first application is the contact information application, the second application is the map application, and the data corresponding to the icon of the first application is a phone number of a user A, the second application may obtain a current location of the user A by using the phone number of the user A. In detail, the second application may request a mobile phone of the user A for a current location of the mobile phone by using the phone number of the user A. Then, the second application may receive a value of the current location of the mobile phone from the mobile phone of the user A, and thus, obtain association information of the first application with the second application.

Additionally, for example, if the icon of the first application is the contact information icon and the second application is the clock application, the device 1000 may obtain current time in a location indicated by an address of a particular user corresponding to the contact information icon, by using address information that is transmitted to the second application.

Additionally, for example, if the icon of the first application is the contact information icon and the second application is the SNS application, the second application may obtain information indicating a number of new messages for a particular user corresponding to the contact information icon, by using an ID of an SNS account that is transmitted to the second application.

Additionally, for example, if the icon of the first application is the contact information icon and the second application is the e-mail application, the second application may obtain information indicating a number of e-mails transmitted to a user of the device 1000 from a particular user corresponding to the contact information icon, by using an e-mail address that is transmitted to the second application.

Additionally, for example, if the icon of the first application is the contact information icon and the second application is the gallery application, the second application may obtain information indicating a number of photographs that include a particular user corresponding to the contact information icon, by using images of photographs that are transmitted to the second application.

Additionally, for example, if the icon of the first application is the contact information icon and the second application is the gallery application, the second application may obtain information indicating a number of photographs that were taken in a current location of the device 1000 (or corresponding to a location of a particular user corresponding to the contact information icon), by using a current location of the device 1000 that is transmitted to the second application.

In operation S5700, the device 1000 may determine whether to display the association information on the icon of the second application. In this case, it may be predetermined whether the association information is to be displayed on the icon of the second application or the association information is to be displayed on an execution screen of the second application.

If it is determined, in operation S5700, that the association information is to be displayed on the icon of the second application, the device 1000 may display the association information on the icon of the second application in operation S5710. The device 1000 may display the association information to overlap with a part or whole of the icon of the second application. Additionally, the device 1000 may display the association information in a periphery of the icon of the second application.
